There is no such thing as free. If you do not pay anything, you know 
you are the product.

I don't think providers would be very willing (understatement) to 
install
your software on their platform that services their other clients. 
I assume this is server side, since you enquire about dovecot.

T-mobile uses dovecot, find t-mobile users ;)
